I recently learned that yet again, Call of Duty has a reference to Zork. Not quite as good as last time where you could actually play Zork I, but there's a mention of "Zork.exe" in a list of files that your character downloads in Call of Duty: Ghosts. See this video of someone playing the game. You'll see the Zork name on the right side of the screen within a second of the video starting at the specified position. https://www.youtube.com/watch?v=kfkvJBO7jzQ&t=11m26s

I also tweeted at Activion's support Twitter account about releasing more Zork games. They said they'd pass on the feedback and that Zork was one of their favorite games. Could be a scripted response, but who knows. https://twitter.com/km3k/status/402526051231731712

Maybe some people at Activision really remember that Zork exists? Do you have any other hints of Zork being remembered by the people at Activision?
